GA-Optimized Co-Design of Jump-Like FlexRay Protocol and Dynamic Control for NCSs and Its Applications

This article is considered with the co-design problem of jump-like FlexRay protocol (FRP) and dynamic control for a class of discrete-time networked systems. A jump-like FRP is proposed to address the constraints of communication resources as well as nonperiodic denial of service (DoS) attacks in the sensor-to-controller communication network. The proposed novel protocol has the characteristics of traditional FRP time-triggered and event-triggered mechanisms. In addition, such protocol is able to avoid selecting sensors affected by DoS attacks. Subsequently, a set of dynamic output feedback controllers related to the selection of sensor nodes is designed to guarantee the finite-time boundedness of the closed-loop system with the prescribed <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math notation="LaTeX">$H_\infty$</tex-math></inline-formula> performance. However, the co-design problem of protocol and dynamic control includes more nonlinear terms, making the problem more challenging to be solved. In order to address the co-design problem and enhance system performance, a genetic-algorithm-based controller design approach has been proposed. Finally, a numerical example and a two-area power system example are given to illustrate the effectiveness of the proposed method.
